If the BIOS and local terminal types are set to VT_100+, some operation options on the BIOS screen cannot be displayed when the user logs in to the BIOS over Serial over LAN (SOL) after the OS at the service side restarts, as shown in Figure 1. LAN refers to local area network.

Figure 2 shows the correct displaying of operation options on the BIOS screen.

Handling Process

The second-last line of operation options on the BIOS screen can be properly displayed after the display mode is adjusted to 80 x 25. For the HyperTerminal provided by Windows, the display mode of 80 x 24 cannot be adjusted. As a result, the last line of operation options cannot be displayed. However, the second-last line provides description of shortcut keys, which does not affect normal operations.

Root Cause

The standard DOS display mode is 80 x 25. If you use the 80 x 24 HyperTerminal to log in, the second-last line displayed on the HyperTerminal will be overwritten by the last line.
